Abstract
PURPOSE: To simplify the total constitution of an exhaust gas cleaner of a fuel injection engine and improve the cleaning performance of its exhaust gas reflux device by making feed-back control using an exhaust gas sensor and by stopping said control at a low and high load operation.
CONSTITUTION: Signals from an intake negative pressure sensor 15, a water temperature sensor 16 and a revolution sensor 17 are input to a microcomputer 14 and the fuel injection amount from a fuel injection nozzle 5 provided at an intake passage 3 is determined in accordance with two amounts in each signal. The intake passage 3 and an exhaust passage 6 of an engine 1 are communicated with an EGR passage 8 having an EGR valve 9. A three way solenoid valve 12 is provided at a negative pressure passage 10 communicating with a negative pressure chamber 9a of the valve 9, and subjected to feed-back-control by the output from an exhaust gas sensor 18. It is also excited by the microcomputer 14 at the low and high load operation to stop the reflux of the exhaust gas.
